Nasco Whirl-Pak

Classic quality and performance

Nasco developed Whirl-Pak®high quality sample bags over 50 years ago and makes them in the U.S.A. The bag's film is a co-extrusion of low-density and linear low-density, virgin polyethylene. This high quality film gives the bags exceptional clarity for easy observation of the sample and superior strength. The film thicknesses vary from 2.25 mils (0.057 mm) to 4.0 mils (0.102 mm) depending upon size and style. Because of the high-quality blended polyethylene, a higher mil thickness is not required to achieve optimal strength.
